This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ63X150-30, with the same bore, stroke, output force, port and mounting, so it fits the same application. The SAI replacement keeps the same ISO 15552 mounting interface, bore, stroke, output force and accessories, so it drops straight into existing fixtures. It is the current-production version of this cylinder with an upgraded piston seal.
Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X150-30
The AirTAC SIJ63 Double Rod Adjustable Cylinder SIJ63X150-30 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 150mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ63X150-30, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X150-30
The AirTAC SIJ63X150-30 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder. An external stop screw lets you trim the extend stroke by up to 30 mm on-site, yielding a usable 120-150 mm window from the 150 mm nominal maximum. As a direct, the SAIJ63X150-30 preserves the exact bore, force, adjust window, and mounting interface.
The SAIJ successor introduces an upgraded two-piece Y-shaped piston seal for lower start-up pressure and longer life. Remember the stop screw sets end position only; it is not a lock, so use an external rod lock for held loads.

Where the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X150-30 Is Used
Variable Depth Forming
Adjust the 30 mm stop screw on-site to tune the extend stroke for material thickness variations in pressing or forming tools.
Adjustable Transfer Pusher
Fine-tune the pusher end position without mechanical shims when product lengths change on the handling line.
Carton Flap Folding
Set precise fold depth on packaging machinery where carton dimensions require frequent field stroke tuning.
Replacing the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X150-30 with the SAIJ63X150-30
To replace the SIJ63X150-30, order the direct replacement SAIJ63X150-30, keeping the 30 mm adjust window (120-150 mm usable extend). Size both ways using 0.5 MPa push force: step down to a 50 mm bore for 982 N, or up to an 80 mm bore for 2513 N. Mounting interfaces (Basic, FA, LB, TC) reuse directly. This SKU lacks the -S magnet, so it cannot accept a magnetic switch; add -S if sensing is needed. For strokes of 300 mm or longer, verify side-load guidance to prevent rod bearing wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ63X150-30
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X150-30 FAQ
Yes, the SIJ63X150-30 is discontinued. The direct replacement is the SAIJ63X150-30, sharing the same ISO 15552 interface, 150 mm stroke, 30 mm adjust window, G3/8 port, and 63 mm bore force.
The external stop screw offers a 30 mm adjust window, making the usable extend stroke 120-150 mm. The stop sets end position only and is not a load lock.
